Both analog and digital modules are available in Opto 22's G1 (or “Standard”) packaging. G1 digital modules offer a wide range of voltage and speed combinations and are available for 5-, 15- or 24-volt logic. Analog modules offer 12-bit resolution. Analog input modules include voltage, current, thermocouple, RTD, ICTD and frequency. Both voltage and current analog outputs are available.

G1 mounting racks include both digital and analog. G1 digital racks are available in 4-, 8-, 16- and 24-channel models and feature LED status indicators and plug-in replaceable fuses for each channel. G1 digital input and output modules can be combined on any G1 mounting rack. A G1 digital rack with screw terminals for both field and logic connections is available for custom application development targeted at isolating non-isolated devices such as PLCs. G1 digital racks are available for both direct connection and connection to Opto 22 Classic brain boards. G1 analog racks in 4-, 8- or 16-channel models accept Opto 22 G1 analog I/O modules. G1 analog racks are compatible with all Classic analog brain boards.
